Question

Find the value of x for which m is parallel to n
A) 10
B) 12
C) 40
D) 52

Answer 1

Answer:  $x=5\textdegree$

Explanation:

Since we have given that

line m and line n are parallel to each other,

So,

Corresponding angles are equal , as shown in the figure ,

According to question,

$19x\textdegree=180\textdegree-17x\textdegree\\\\19x\textdegree+17x\textdegree=180\\\\36x\textdegree=180\textdegree\\\\x=\frac{180}{36}\\\\x=5\textdegree$

Hence, $x=5\textdegree$
